Fuel leaking from carb in my TC3

I need some help. I just bought this car and I went to prime the engine to run the first time and fuel begun to leak from the seal at the carb. Anyone know how to fix this as I cant figure out how to take the carb off and push it down lower.

Re: Fuel leaking from carb in my TC3

Not sure if the TC3 has a generic style engine but there is most likely an O-Ring on that carburetor where it enters the block. Usually they would leak air into the engine not so much fuel out. But if your sure thats where it is coming from loosen the screw holding the carburetor in. Then try and push out the insert thats inserted in the block. That insert has a flat spot on it which allows the carburetor to slide in and provides a nice pinch when the bolt is tightened. If the flat spot is not in the correct position you will never slide the carb all the way in. Hope this helps

Re: Fuel leaking from carb in my TC3

Go to Canadian tire to the automotive section. Pick up a tube of SENSOR
SAFE SILECONE (the orange colour)
Take your carb out and put some of it around the collar. Not to much you don't want any to
fall in the motor. Put the carb in place and leave it over night.
That will for sure fix any air leaks. It's cheap it's easy and you will have enough SILECONE
to last you a life time.
